LabVIEW Reduces Development Time For Hardware-In-The-Loop Systems

AUSTIN, Texas—(BUSINESS WIRE)—Oct. 18, 2005— National Instruments (Nasdaq: NATI) today announced the NI LabVIEW Simulation Interface Toolkit 3.0, the latest version of the company's software that gives control system design and test engineers a seamless link between the NI LabVIEW graphical development environment and The MathWorks Inc. Simulink(R) software. With the LabVIEW Simulation Interface Toolkit 3.0, engineers now can reduce development time for hardware-in-the-loop systems with new configuration-based deployment to CAN and FPGA I/O; run-time parameter selection; and thread scheduling for multirate models.

Engineers can use configuration-based functionality in the LabVIEW Simulation Interface Toolkit 3.0 to easily create custom hardware-in-the-loop test systems with the National Instruments I/O of their choice, including CAN, reconfigurable I/O (RIO) and CompactRIO FPGA-based I/O, in addition to existing NI data acquisition I/O support. The software's configuration dialog makes it easy for engineers to generate VIs for real-time implementation by simply mapping I/O channels to model inports and outports.

"Configuration-based I/O helped us to implement complex functionality such as the generation of application-specific signals in a fraction of the time otherwise required," said Orazio Ragonesi, automation and simulation engineer at MicroNova. "NI LabVIEW makes our software development much faster compared to development with C/C++ and VHDL."

With the LabVIEW Simulation Interface Toolkit, engineers can build custom LabVIEW user interfaces to view and control a Simulink model during run time. Engineers working with very large models now can use the LabVIEW Simulation Interface Toolkit to remap controls and indicators to different model parameters and signals during run time. With this ability, they can easily scale user interface size and complexity by reusing controls and indicators.

For engineers with large, complex models, the LabVIEW Simulation Interface Toolkit now automatically imports model subsystems with different rates defined in Simulink and schedules separate threads in the LabVIEW Real-Time Module. For complex systems, engineers can take advantage of the efficiency that rate monotonic thread scheduling offers with a single processor rather than using a multiprocessor system. Also, in a single step, engineers using the LabVIEW Simulation Interface Toolkit 3.0 can simultaneously modify numerous parameter values and seamlessly test multiple conditions during run time.

By combining the LabVIEW Simulation Interface Toolkit 3.0 with the CompactRIO embedded control system, engineers can use built-in FPGA functionality to create real-world implementations of control models for rapid control prototyping. Engineers also can take advantage of the built-in FPGA functionality and powerful PXI processor using NI R Series devices that easily integrate with the new toolkit for creating large-scale hardware-in-the-loop test systems.

Educators also benefit from the LabVIEW graphical interface to intuitively control and view data within their control models. To learn about educational discounts for qualifying academic institutions, readers can visit www.ni.com/academic.
